In-situ characterization of Pt nanoparticle disintegration during CO oxidation on hybrid oxide supports

HAADF-STEM images of the hybrid supporting oxide a) and the resultant Pt-containing catalysts b–d). e) In-situ tracking of Ce⁴⁺ concentration and temperature for the in situ XAS and STXM CO oxidation (1 vol.% CO +4 vol.% O₂ + 95 vol.% Ar) experiment. f) Enhanced specific mass activity of PCT during repeated and prolonged CO oxidation reaction. The MA of Pt was increased by 3.3 times from PCT-1 to PCT-10 h. The MA of PT catalyst without Ce addition was increased by 9.6 times upon adding 2 wt.% of Ce (from PT to PCT-1).
